Application filed September 12, 1913.

' To all whom it may concern Be it known that I, FLORENCE D. ROBERTS, acitizen of the United States, and a resident of Montclair, in the countyof Essex and State of New Jersey, have invented certain Improvements inEraser-Brushes, of which the following is aspecification.

The objects of this invention are to provide an eraser brush adapted tobe removably aflixed to an eraser of ordinary construction; to enablethe brush to be removed at pleasure and the eraser used without it; toemploy a frictional engagement of the brush attaching means with theeraser, so that it is readily applied. or removed; to take advantage ofthe resiliency of the eraser in using the brush; to secure a simple andcompact construction, with few parts, not liable to get out of order,and to obtain other advantages and results as may be brought out in thefollowing specification.

Referring to the accompanying drawings, in which like numerals ofreference indicate the same parts throughout the several views, Figure 1is a side view of an ordinary circular. eraser with my improved brushapplied thereto; Fig. 2 is a sectional view on line AA Fig. 1; Fig. 3 isa sectional view on line BB of Fig. 1; Fig. 4 is a side view of a brushalone, showing the brush proper at right angles to the attaching means;Fig. 5 is a view similar to Fig. 1, showing a modified form of attachingmeans for the brush; Fig. 6 is a sectional view on line C-C Fig. 1, andFig. 7 is a similar sectional view illustrating a still furthermodification ofattaching means. V

In the specific embodiment of the invention illustrated in saiddrawings, the reference numeral 1 indicates an ordinary circular eraserto which I have shown my improved brush applied, but it is to beunderstood that my invention is equally applicable to other forms oferasers, and I do not wish to restrict myself to any particular style.The eraser brush comprises attaching means and a brush proper carriedthereby, said brush having a sweeping portion of any suitable material,although I have shown bristles for illustration. I

In the preferred construction, shown in Figs. 1, 2 and 3, the attachingmeans comprises a single piece of sheet metal doubled as at 2 to providea pair of spaced jaws 3, 3 adapted to grip between themselves a marSpecification of Letterslatent.

ginal portion of the eraser 1. These jaws 3, 3 are bent at their edgesaway from the eraser to lie fiatwise together, as at 4, 4 and thecontacting portions are preferably of sufficient size to receive aneyelet 5 which is passed through registering apertures and the twocontacting portions 4, 4 of the sheet metal thereby clamped together.From these contacting portions 4, 4 extend ears 6, 6 lying flatwisetogether in the planes of the portions 4, 4 and preferably projectingtherefrom adjacent to the gripping jaws 3, 3, said ears being integrallyjoined at their outer ends at the line of doubling or folding 2.Furthermore, said ears provide between themselves a socket 7 to receivea stem 8 of the brush proper, said stem being gripped and held in fixedrelation to the ears 6, 6 when the eyelet is riveted into place. h

It will be obvious that the direction in which the ears 6, 6 extend fromthe contacting portions 4, 4 of the attaching means may be varied tosuit the taste or desire of those making the article, without departingfrom the spirit or scope of the invention, and that to vary thedirection of the cars will result in supporting the brush at acorresponding deviation from a radial line of the eraser. For instance,in Fig. 4 I have shownears 16, projecting oppositely from the jaws 13,so that the brush proper lies at right angles to its position as shownin Fig. 1 or tangential to an eraser to which it may be'applied.

The brush proper I have shown in Figs. 1 to 4 inclusive consisting of atuft of bristles 9 seated in the flattened and enlarged end 10 of atubular holder, or ferrule the other end of which is reduced to form thestem 8 which enters the socket 7. Obviously any other suitable andequivalent construction could be employed, however.

In Figs. 5 and 6 a brush proper is shown applied to an eraser 1 byattaching means comprising a U-shaped clip 11 with jaws 23, 23 adaptedto grip the eraser, and apertured at its bottom, as at 12, to receive areduced stem 28 of a ferrule whose bristleholding portion 20 provides ashoulder 14 outside of the aperture to prevent inward displacement.After the stem is inserted in the aperture 12, its inner end is spreadto retain the ferrule firmly in place, and solder may be applied to thejoint, as well, if desired. In this form of the invention, I have shownthe jaws 23, 23 adapted to project under the side plates 15, 15 of theeraser, but obviously they could terminate short of said side plates 15,15, if desired, as the jaws 3, 3 are shown in Figs. 1 and 2, or saidjaws 3, 3 could be extended if desired like those in Figs. 5, 6 and 7.Or, in any pair of jaws,

one could be long enough to enter beneathchange might also be made inthe construction shown in Figs. 1 4c, and the bristles inserted directlyinto the socket between the ears 6, 6. i 1

Many. other modifications of construction can be made without departing,from the spirit and scope of the invention, and I do not wish to beunderstood as restricting myself except as required by the following"claims when construed inthe light of the prior art. By my'invention thebrush is attached to the eraser so that in using said brush by theeraser as a handle the resiliency 0f the eraser is imparted to thebrush, and thus a softness. of pressure in brushing is secured whichguards against any possible injury or harshness. It will be understoodthat in the" class of erasers to which this-invention relates the.eraser is grasped by the fingerand thumb pressing upon opposite sides ofit against the two plates. 15, 15, and thus by the attachment of thebrush as set forth herein the resiliency of the exposed peripheralmargin .of the rubber is secured in the'use of thebrusli. Furthermoresuch resiliency may be secured in a varying degree, according to whetherthe brush is attached as in Fig. 1, with a single [jaw 23 underlyingoneof the plates 15 or with both jaws entering beneath said plates.'Obviously in all these cases some resiliency is obtained, and theamountbest adapted to the work to be done will determine which constructionshall-be used.

Having thus described the invention what I claim is:

'1. The combination with an eraser comprising a} rubber, disk withcentral plates at opposite sides thereof of smaller diameter than saidrubber and aifording a grasping portion,,of a brush attached to the edgeof said rubber disk outside the metal side plates,'whereby advantage istaken of the Copies of this patent may be obtained for resiliency of therubber in using the brush when the eraser is grasped by its side plates.

2. The combination with an eraser comprising a rubber disk with centralplates at opposite sides thereof of smaller diameter than said rubberand affording a grasping portion, of attaching means having armsengaging the rubber disk outside said side plates and conforming betweensaid arms to the edge of said rubber disk and fitting thereagainst toprevent swinging in the plane of the eraser, and a brush carried by saidattaching means, whereby advantage is taken of the resiliency of therubber in using the brush when the eraser is grasped by its side plates.

3. The combination with an eraser comprising a rubber disk with centralplates at opposite sides thereof of smaller diameter than said rubberand afiording a grasping portion, of attaching means having armsfrictionally engaging the rubber disk outside said side plates, saidarms being extended circumferentially of the rubber disk, and a brushcarried by said attaching means, whereby advantage is taken of theresiliency of the rubber in using the brush when the eraser is graspedby its side plates.

i. The combination with an eraser comprising a rubber disk with platesat opposite sides thereof of smaller diameter than said rubber, ofattaching means comprising a piece of sheet material doubled to form asocket at the line of doubling and jaws at the same side of said line ofdoubling as said socket, means clamping the doubled portions togetherbetween said socket and jaws, and a brush mounted in said socket.

5. The combination with an eraser comsite sides thereof of smallerdiameter than said rubber, of attaching means having re silient armsgripping the rubber disk between themselves and projecting at theirextremities beneath the side plates.
